Phenolic composites offer outstanding long-term engineering performance when exposed, under load, to elevated temperature. Additionally phenolic composites have excellent chemical resistance, electrical insulation, surface hardness, and dimensional stability.
We manufactures phenolic cotton molding products such as the bush, liner, gear and etc. Follow are the processing steps:
① According customers’ drawing or samples to make the molds.
② According the different application, we will use the different types of cotton cloth to produce the prepreg.
③ Calculate how much prepreg need to fill into the mold and cut the prepreg into the different shapes and put them into the mold.
④ Under the high pressure and high temperature from the press machine to keep certain time and to ensure the prepreg completely cured into the wanted shape.
⑤ Take out the phenolic molding blank part and move off the molding flash, then machine it by CNC machines to final products.
